I don't know much about how a Yakuza works but this movie was interesting enough to keep me watching until the end. I thought the colour grading in this was good but I don't know whether it's the way the movie was written or due to the editing choices in post production but I wasn't a huge fan of the way scenes cut and jumped between each other. As a result of, I found some parts jarring to watch.
The plot was alright but the pacing seemed a little rushed towards the ending. And because the ending was wrapping up quickly, some scenes were anticlimactic. I was watching and actually went, "oh is that it?" I wouldn't say I was disappointed but I thought it would've ended in a bang or something.
As for the characters, they weren't bad but their characterisation could've been better. I thought the characters were overall quite shallow but whatever, since this movie is most likely plot driven. The action scenes were good too, they were violent but not explicitly so.
